ABSTRACT
The constant influence of the human-being in animal management activities, besides increasing the cost of production, becomes a source of animal stress; which generates the most important signs of the process, acting as a bio-sensor that needs to be measured in a continuous and direct way. From the many available options to obtain an animal temperature parameter, the measurement of external temperature proves to be a less invasive method. Fuzzy system, based on fuzzy logic, works with inaccurate information and converts them into a mathematical language with easy computational implementation. Therefore, this work aims to use fuzzy logic as a tool for assessing the degree of swine thermal comfort, using variables data entry related to the environment and the animal. For this purpose, a simulation using Microsoft Excel software was performed with the possible environmental conditions of the region of Piracicaba (Dry Bulb Temperature - Ts and Relative Humidity - UR), interacting with the local altitude (z) and potential tympanic piglets temperatures (TiF) using equations 1 and 2 adapted from Mostaço (2014). After performing the simulations, Rectal Temperature (TR) and respiratory frequency (FR) data obtained were crossed with FR, TR and critical temperatures for condition of thermal comfort of piglets (5th to 8th week) values, proposed by Mostaço (2014) through the fuzzy logical t
